ATTACHMENT" FOR HARVES'IERS.

' Specification of Letters. Patent. Patented Mar. 26, 1912.

Application filed August 15, 1910. Serial No. 577,366.

I drawings, forming part of this specification,

Figures 1 and 2 are plan views showing a portion of a corn harvesterhaving my invention applied thereto; the two figures showing differentforms of the invention.

Considerable difliculty is experienced in the operation of cornharvesters, corn cutters, huskers, and cane cutters, harvesters, and thelike, by reason of grass, weeds, and other foreign matter, which is cutor pulled with the corn and is elevated and carried into the machinewith the corn. This grass and other foreign matter winds into themachinery, clogs the elevator, and the knives, or stops machineryentirely.

The object of my invention is to provide a simple device which can bereadily attached to various kinds of these machines, either new or old,and which will entirely overcome this difficulty. This objectv isaccomplished by the provision of a bar or lever placed in the throat ofthe machine in advance of the knives, and which acts to bend over weeds,grass, etc., and keep such weeds and grass from passing into the knives,while permitting the corn stalks to pass readily to the knives.

Referring first to the form of my invention shown in Fig. 1, thenumerals 2-2 designate the throat-forming bars or guides of a corncutter or harvester, these bars or guides forming the passage throughwhich the stalks are guided to the usual reciprocating knife or cutter3. Placed transversely across this throat, preferably at the under sidethereof, is a bar or lever t, pivoted at 5, and having a spring 6attached to one arm thereof. The opposite bar is provided with asuitable stop 7 for limiting the forward movement of the free arm of thelever.

The operation is as follows :The resistance of the spring 6 is madesufficiently great so that all weeds, grass, and the like which contactwith the bar or lever will be bent downwardly and prevented from passingfarther into the throat to the knives. When, however, a corn stalkstrikes the bar 4, the resistance of the spring is overcome and the freearm of the bar moves backwardly and permlts the stalk to pass to theknives.

In the form of my invention shown in Fig. 2, instead of a single bar orlever of the character described, I' provide two of these bars or levers8 and 8 pivoted to the throat or guide bars 2 and each having a spring9. The operation of this form of the invention is substantially the sameas that of the form first described, but has the advantage that wherecorn comes in on one side of the knife it will keep grass and weeds outof the other side, and will thus be more efiective than the single baror lever. As soon as the corn stalk has passed the bar or lever, or thetwo bars or levers, the spring or springs will pull the latter back toplace. The knife, therefore, will only out such grass or weeds as areclose to the hill, and these going inward with the corn stalks do notcause any difliculty, as the stalks are stiff and carry the weeds backwith them. The lever being attached to the under side of the framestrikes the corn stalks so low down and near the ground that it does notbend the corn down, but will bend down all ordinary weeds, grass, andgrain, so that the knife passes overthem without cutting. My inventionalso obviates the trouble which has heretofore been experienced inmaking turns at the end of corn fields where there is apt to be more orless weeds, grass, etc., and also in driving to and from the field.Heretofore, the machines would clog up with grass and weeds and have tobe stopped and cleaned before starting to out. o

By the use of a device of this character on a cane harvester, the majorportion of the grass and weeds will be eliminated from the harvestedcane which will greatly enhance its value, as the juice from the caneafter the cane has been passed through the crusher will be free from thejuice of grass and weeds.

The device can be readily attached to various makes and kinds ofmachines at relatively small cost; and if any particular piece of cornis so clean as to make the use of the device unnecessary, it can bequickly and readily detached and removed.

I do not desire to limit myself to the exact forms of my invention whichI have herein shown and described, as it will be obvious that the formand arrangement of the bars or levers and their exact mode of attachmentto the frame of the machine may be considerably varied Without departingfrom the spirit and scope of my invention as defined in the appendedclaim.

What Iclaim is y Y A harvester having cutters, a stalk guiding throat, apivoted bar extending in a horizontal plane transversely of the throatdirectly in front of the cutters and in substantially the samehorizontal plane With the cutters and having its front face atsubstantially right angles to the longitudinal center line of thethroat, a spring connected to said bar, said spring having a resistancesufiicient to cause the bar to bend over Weeds and the like when saidbar is pressed agamst them, but yielding to permit movement of my hand.
